Patent DE-1966826-A1 (DE)
Title: Car window-heating resistance strip
Inventor: ZOCCOLINI GINO
IPC: C03C17/06
Filed: 1969-09-26
Abstract: Heated window comprises strips connected by resistance strips of different lengths obtained by depositing and hardening of a suspension of metallic silver and a layer of melting glass, in which the resistance strips have a linear resistance different from adjoining ones by being of different section or by differing ratios of metallic silver: glass in the strips. Specif. the resistance strips are reinforced by the electrical deposition of a metal. Specif., the resistance strips may have the same cross-section and be at the same distance, but made of different materials resulting in the same surface heating of the window. Pref., the amount of vitrous material is of higher resistance than that of the suspension containing the metallic silver is added to it in amounts differing in ratios for each strip, pref. between 30-50% by wt. Specif., the strips are fitted on the windows by device rolling over the windows without slipping and which have cavities regularly distributed along their periphery and suitable for applying it in a ratio to their filler content and the area of the window. Heating material can be deposited on the window with predetermined heating capacity independent of speed of application.
